The textile industry is at a critical crossroad, where sustainability alone is no longer sufficient; a shift toward the regeneration of resources is essential. The major stakeholders in the textile sector need to examine the limitations of conventional textile production, including environmental degradation, over-reliance on finite resources, and challenges in waste management, and highlight emerging regenerative approaches that can redefine the industry. Innovative resource mixes in textiles can drive this transformation, which is the need of the hour. The future of textiles lies in regeneration and resource mix, moving beyond sustainability to actively restore ecosystems, enhance biodiversity, and minimise waste. This chapter, The Future of Textile Resource Mix: Towards a Regenerative Industry, examines the limitations of conventional fibre choices such as natural, synthetic, and blended, while highlighting regenerative alternatives that promote ecological balance. The chapter envisions a regenerative textile industry that restores rather than depletes, urging collaboration between fashion, agriculture, and biotechnology to create a net-positive impact.
